Outstanding Facts About Thiopaq Process

<p style&equals;"text-align&colon; justify&semi;">In <strong>thiopaq process<&sol;strong>&comma; both sulphur recovery and gas purification processes are integrated into a single unit&period; First of all&comma; the gas will come in contact with the solution present in the absorber and then absorb H2S leading to the formation of sodium sulphide&period; The sweet gas will not leave the absorber&comma; and it will then be available for further processing or direct use&period;<&sol;p>&NewLine;<p style&equals;"text-align&colon; justify&semi;">The processes that follow the sulphide-loaded solution are determined by the pressure of the sour feed gas&period;  The gas gets directed to a bioreactor or a flash vessel&semi; the bioreactor operates at ambient temperature and atmospheric pressure&period; In this chamber&comma; elemental sulphur is formed from the reaction between the sulphur and microorganism&period; The solution obtained is then passed over the absorber to be re-circulated&period; Part of the said product is also directed to the sulphur recovery section&period; This way&comma; the system can be rid of any <strong>elemental sulphur<&sol;strong>&period;<&sol;p>&NewLine;<p style&equals;"text-align&colon; justify&semi;"> A decanter centrifuge can then be used to separate the elemental sulphur produced from the solvent&period; Water is recovered in the process&comma; and it is then recycled via the bioreactor to the thiopaq process&period; There is a given level of salt that should be accumulated in the system&period; The salt level is prevented from becoming excessive by bleeding the system using a small slipstream&period;<&sol;p>&NewLine;<p style&equals;"text-align&colon; justify&semi;">In summary&comma; <strong>thiopaq<&sol;strong> is more or less a desulphurization process of biogas&period; The very first commercial unit for this purpose was built in the Netherlands in 1993&period; The product obtained had been used for several processes in the industrial world since then&comma; and many more units have been built after then&period; The unit built in 2002 in Canada stands among the first for the commercial process in the natural gas industry&period; This technology has won the Sellafield award for engineering excellence in 2007&period;<&sol;p>&NewLine;<p style&equals;"text-align&colon; justify&semi;">The entire process involved is environmentally friendly&period; It is a desulphurization process just perfect for the complete removal of H2S and also for the conversion of the H2S to elemental sulphur using sour gas streams as the raw material&period; The fact that thiopaq makes use of naturally occurring bacteria to form elemental sulphur from H2S makes this process to be unique&period; The product formed from the entire process can be used in the production of fertilizer for agricultural processes&comma; amongst other applications&period;<&sol;p>&NewLine;<p style&equals;"text-align&colon; justify&semi;">The first group to market this process for biogas treatment is Paques BV&period; The biogas used in the process is produced by anaerobic digestion of wastewater&period; The process stands as one of the best ways to recover sulphur and transform it into several useful products&period;<&sol;p>&NewLine;<p style&equals;"text-align&colon; justify&semi;">The benefits of thiopaq process are numerous&period; For one&comma; it helps to reduce the need for chemicals that are needed for liquid redox processes&comma; reducing the chemical requirements to nutrients and sodium hydroxide only&comma; thereby reducing operating costs&period; Also&comma; the process can be easily operated in ambient temperature without requiring reboilers&comma; burners or any other equipment&period; Since the process involved in the recovery and regeneration of sulphur can be operated under ambient temperature and pressure&comma; then capital expenditure of the process will be highly reduced&period;<&sol;p>&NewLine;<p style&equals;"text-align&colon; justify&semi;">One other thing that makes thiopaq process a suitable process is its ease of operation&period; The sulphur produced as a result of this biological process is hydrophilic&period; As a result&comma; plugging process is eliminated&comma; remaining that very little attention will be required from the operator&period; The process is equally safe&period;<&sol;p>&NewLine;
